TS-570D PTT issue

My PTT is setup on com5 via my Rigblaster com port emulator. (The rigblaster is seen as com5 via a usb to my Vista machine) It works in other apps. I KNOW the difference between software command (which I use on HRD/DM780 for digital modes via usb to serial on com 6, this is a CAT command) and the hardware keying setup on com5.

WSPR will not engage my PTT. If I manually engage it, it WILL DROP the PTT when it finishes transmitting. Very frustrating. I know for fldigi, I had to tell the software to use RST on the com port but there is not this provision on WSPR as far as I can tell.... the 570 doesn't work with VOX from the audio in the back, only on the mic so I need to resolve this somehow!

For issues with this site, email the WSPRNET Admin Team or post to the site forum. Downloads and more information about WSPR program and the MEPT_JT mode, as well as other modes by Joe Taylor (K1JT), can be found at the WSJT Home Page.
